AIR-GUN.

intensa 1 Specification of Letters Patent.

Patented Nov. i 1, wie.,

Be it known that l, ARTHUR V. Dlcnnr, a citizen of the United States,residing at Seattle, in the county of King and State of e lVashington,have invented certain new and useful. Improvements in Air-Guns, of whichthe following is a specification.

This invention relates to air-guns and,

more especially, to improvements'in the gun of this class which isillustrated and described in United 4States Patent 1,026,303, issuedtome May 14, 1912.

The object of my improvements is to provide an extremely ellicient andconveniently ,operated air-gun which will embody rclatively few andcolnpactly arranged parts and be 'capable of withstanding severe usagewith little liability of getting out of order.

With these ends in View, the invention consists in the improvedconstruction, adaptation and combination of parts, which will be'described hereinafter, and pointed out .more particularly in theappended claims. In the drawings, Figure 1 is a side eleva- .tion of agun constructed in accordance with the present invention. Fig. 2 is avertical longitudinal sectional View thereof. Fig. 3 is a fragmentaryside elevation with the cover plate removed. Fig. 4 is a detailhorizontal section through 4-4 of Fig. 1.

The reference numeral 5 designates the frame of the gun which is rigidlycpnnected to the stock 6. Secured to the stock is a longitudinallyarranged cylindrical ytube 7 5 which serves Aas a reservoir forcompressed air, and extending through the tube 7 is the gun barrel 8.

9 is the fore-arm incasing a pump cylind'er 10 which is provided with aplunger The latter is operated by means. of a lever 12 which is hingedlyconnected to the front end of the tube 7 and is connected by a link 13to a block 14 Which is slidable upon a guide-bar 15, the block in turnbeing connected to the plunger bya piston rod 16. When the lever 12 isunemployed, it is se- Cured in juxtaposition with the tube 7 by means ofa collar 121 which is moved endwise upon' the pum cylinder to couple thepd olf said lever t creto, as represented in 17 represents a passageleading from the rear, or discharge end of the pump to the interior ofthe air reservoir 7, (and 18 is a dot extending from said passage to therear of the gun barrel. VProvided in the pump cylinder' is aspring-pressed valve 19 which serves to prevent the'reverse flow of airfrom the passage 17 into'the pump cylvalve 20, which is yielding-ly heldby a spring 21 in closed position against a seat 201, is provided at thejuxictureof the passage 17 and duct 1S.

Provided in the stock 6 and to the rear of the gun barrel is a bulletmagazine comprising a tube "22 having au open front end which isconnected by a way 23 with a cylindrical. chamber 181 extendingtransversely through the air duct 18.

The axis of the chamber 181 is disposed in the same plane with thelaxisof the gun barrel. Provided centrally of said chamber is a non-rotatablecylindrical core or plug 24 formed with a bore 241 extendingdiametrically therethrough and in coincidence with the bore of thebarrel. Rotatably mounted upon the core 24 and fitting the peripheralwall ofsaid chamber is a sleeve 25 provided with holes 251 and 252disposed diametrically opposite each other and are arranged to4 bebrought into axial aline' ment with the barrel bore 81 and the core bore241 when the sleeve is in its normal rotary position, as shown in Fig.2. When the sleeve is moved into the rotary position in which it isindicated by broken lines in Fig. 3, the hole 251 is presented to theway4 23 to receive a projectile from the magazine.

The bullets, indicated by 26, within the magazine are pushed forwardthrough the Way 23 into feeding positions with respect to the 'sleeve bymeans of a follower 27 which is urged forward by a helical spring 271. Astud 28 secured to said follower protrudes through a slot 29 provided inthe magazine wall Vand is utilized for retracting the follower ino-pposition to spring 271 when the magazine is to be supplied withbullets through an aperture 291 provided therefor in the Wall of themagazine.

Tothe rear of the valve 20 is av chamber 30 containing the main spring31 tending to press a hammer-'block 32 forwardly to encounter a firingpin 33 which,y in turn, is driven by the spring-impelled block 32against the valve 20 to unseat the same when' the block is released.lVhen the hammer? block 32 is brought, through the agency of a stud 321,to its rearmost position, it is engaged by a detent 34 which is in thenature of a bell-crank lever having a depending arm 341 which isconnected by a pull-rod 35 with the trigger 36. The engagement of saiddetent with the hammer-block is effected by a spring 37.

Provided on the sleeve 25 is an arm 38 which is connected by a pin 381to a dog 35) which is connectecsat its forward end with an extensiblespring 40 tending to yieldingly retain the sleeve in the position inwhich it is shown in Fig. 2. This dog is of a length to have its forwardhooked end engage the stud 321 which is rigidly connected to thehammer-block and protrudes through a longitudinal slot- 41 provided inthe plate 42 secured to the side of the gun,

43 is a Xed pin disposed so as to be encountered by the inclined face391 of the dog to ward off the latter from the stud 321 as thehammer-block (see Fig. 3) approaches the position in which it is engagedby the detent 34. When the dog 39 is, through the medium of the stud321, drawn rearwardly, the sleeve251 is presented to the way 23 toreceive a bullet, and upon being released, the spring 40 asserts itspower to restore the sleeve 25 to normal position (Fig. 2) with thebullet in tiring position. The connection between the spring 40 and thedog 39 is offset to be below the longitudinal axis of the latter inorder that the spring will exert a downward pressure at the hooked endof the dog.

To fire the gun, the trigger is pulled, thereby withdrawing the detent34 from the hammer-block 32, whereupon the main spring 3l becomesoperative to drive the hammer-block against the ring pin 33 which isthereby caused to push the valve 20 into open position for the'admission of a quantity of compressed air into the duct 18 to actagainst t-he bullet and deliver same from the gun.

' What I claim isl. In an air-gun, the combination of a rotarybullet-feeding` element arranged to carry a bullet from the magazine tothe rear end of the gun barrel, a hammer block and connections with thefeeding element mov-- able longitudinally ofthe gun for effecting therotary movement 'of said element vinto bullet-receiving position, and aspring for rotating the element into position for discharging thebullet.

- 3. In an air-gun, the combination of la rotary bullet feed elementprovided with an aperture in which a bullet is conveyed from themagazine to the rear of the barrel', a spring operatively connected tosaid element, a spring-pressed valve, a spring-pressed hammer-block foractuating said valve, a detent, means for moving said block into posi-Ation to be engaged by said detent and also serving in coperation withsaid spring to operate the aforesaid bullet. feed element, and triggeractuated means for releasing said detent from the hammer-block.

4, In an air-gun, the combination of a rotary bullet feed element, aspring pressed valve, a spring-pressed hammer-block, a detent, means formoving said block into position to be engaged by said detent and alsoserving to rotate the aforesaid element into position to receive abullet from the magazine, a. spring for actuating s'aid element toconvey the bullet into yfiring position, and means for releasing saiddetent from the hammer-block whereby a quantity of air is supplied 'tothe rear of the bullet for discharging the same. i

5. In an air-gun, the combination with the magazine and the barrel, of anon-rotatable plug having an opening disposed in alinement with thebarrel-bore, a sleeve mounted for rotary movement on said plug andprovided with apertures disposed at diametrically opposite sidesthereof, one of said apertures serving as a receptacle in vwhich abullet is conveyed from the magazine into firing position, and a hammerblock and connections with the sleeve for effecting movemont of thelatter into bullet receiving position.
